OLR Bill Analysis 
sSB 961  
 
AN ACT CONCERNING CERTAIN SEWAGE DISPOSAL SYSTEMS 
AND ALTERNATIVE SEWAGE TREATMENT SYSTEMS.  
 
SUMMARY 
This bill transfers from the Department of Energy and 
Environmental Protection (DEEP) to the Department of Public Health 
(DPH) regulatory authority over small community sewerage systems 
with daily capacities of up to 10,000 gallons.  
By law, DEEP already delegates regulatory authority to DPH over 
(1) household and small commercial subsurface sewage disposal 
systems (generally, septic systems) with daily capacities up to 7,500 
gallons and (2) alternative on-site sewage treatment systems with daily 
capacities of up to 5,000 gallons. The bill increases both these 
thresholds, and therefore the maximum capacity of facilities under 
DPH authority, to 10,000 gallons.  
The bill does so by requiring the DEEP and DPH commissioners, as 
applicable, to adopt regulations effectuating the jurisdictional transfers 
before July 1, 2023. 
EFFECTIVE DATE:  Upon passage 
SEPTIC SYSTEMS AND S MALL COMMUNITY SEWER AGE 
SYSTEMS 
The bill increases the size of septic systems over which DPH and 
local health departments, rather than DEEP, have jurisdiction from a 
maximum daily capacity of 5,000 gallons to a maximum daily capacity 
of 10,000 gallons. It also shifts from DEEP to DPH jurisdiction over 
small community sewerage systems with a maximum daily capacity of 
10,000 gallons. Community sewerage systems are comprised of one 
subsurface sewage disposal system serving at least two residential 
buildings.  2021SB-00961-R000558-BA.DOCX

Under the bill, DEEP must adopt regulations before July 1, 2023, 
establishing and defining the systems subject to DPH authority. Under 
existing law, DEEP delegates to the DPH commissioner authority to 
issue permits and approvals for certain household and small 
commercial subsurface disposal systems. DPH must then establish 
minimum requirements for these systems in regulations and 
procedures for local health directors or sanitarians to issue permits or 
other approvals. 
ALTERNATIVE ON-SITE SEWAGE TREATMEN T SYSTEMS 
Before July 1, 2023, the bill requires the DPH commissioner to adopt 
regulations establishing and defining discharge categories that are 
alternative on-site sewage treatment systems with a daily capacity of 
up to 10,000 gallons, instead of up to 5,000 gallons as current law 
requires. As with existing law, DPH must do so within available 
appropriations. (To date, none of these regulations have been adopted, 
and DEEP is currently responsible for permitting all of these systems.) 
Existing law gives the DPH commissioner jurisdiction over 
alternative on-site sewage treatment systems after the adoption of 
associated regulations, including the ability to issue or deny permits 
and approvals for these systems. An alternative on-site sewage 
treatment system consists of a sewage treatment system that uses a 
treatment method other than a subsurface sewage disposal system and 
involves a discharge to groundwater. 
BACKGROUND 
Related Bill 
sSB 1024, ยง 11, favorably reported by the Planning and 
Development Committee, also (1) increases the size of alternative 
sewage treatment systems over which DPH has authority, but from a 
maximum daily capacity of 5,000 gallons to a maximum daily capacity 
of 7,500 gallons, and eliminates the caveat that it is within available 
appropriations and (2) gives DPH authority over community sewer 
sewage systems with a maximum daily capacity of 7,500 gallons.
